Operation of Unshielded Kinetic-Inductance Traveling-Wave Parametric Amplifiers in Multi-Tesla Fields
Christian Boutan, Erik Lentz, Corwin Shiu +12
Cryogenic parametric amplifiers are used to amplify radio-frequency signals for a range of applications in basic and applied science. Both Josephson Parametric Amplifiers and Josep…
Precise 2D electric field density simulations for superconducting quantum devices
Zydrunas Gimbutas, Wei-Ren Syong, Nhi Nguyen +5
Dielectric loss due to two-level systems is a limiting factor for superconducting qubit relaxation times. These losses arise mostly from nanometer-scale interfacial defect regions…
Imaging the Superconducting Proximity Effect in S-S'-S Transition Edge Sensors
Austin R. Kaczmarek, Samantha Walker, Jason Austermann +11
Proximity effects at superconducting interfaces, between different superconductors (S-S') or between superconductors and normal metals (S-N), are fundamental to the performance of…
Impact of embedded Ho on the performance of the transition-edge sensor microcalorimeters of the HOLMES experiment
Douglas Bennett, Matteo Borghesi, Pietro Campana +19
We present a detailed investigation of the performance of transition-edge sensor (TES) microcalorimeters with Ho atoms embedded by ion implantation, as part of the HOLMES e…
